    Ingredients

    Before you start to make this lazy cake recipe, measure and prepare your ingredients so the cooking process will go smoothly and easily.

    Butter- use unsalted butter for this recipe. Only butter will work for this recipe, no margarine, and no coconut oil. Margarine has a weird taste and can ruin the flavor of these delicious cookies.

    Dutch cocoa powder– we like to use Dutch-process cocoa powder for our chocolate cake because we like the deep and rich chocolate taste, but the natural cocoa powder will work great as well!

    Granulated sugar– we like to use granulated sugar, also the most common sugar used in baking. Caster sugar will work great as well.

    Water- use room temperature water.

    Vanilla extract- Vanilla extract Is an essential ingredient for chocolate cake.

    Vanilla wafers- you will need vanilla wafers for this recipe. If you don’t have vanilla wafers (or vanilla biscuits), you can use vanilla tea biscuits and digestive biscuits.

    For the chocolate ganache

    Chocolate- use the best quality semisweet or dark chocolate bars for the best flavor. using the best quality dark chocolate is very important in this recipe.

    Heavy cream- use full-fat heavy cream for this recipe. the heavy cream makes this chocolate cake. This cant is substituted.

    Assembly

    Nuts- we used walnuts in this recipe but you can make this recipe with any toasted nuts that you like most like hazelnuts, almonds, pistachios, etc. we highly recommend toasting the nuts before putting them on the cake.

    •  Make sure you line your baking pan with parchment paper to prevent the cake to stick to the pan.

    Faq's

    Can I use regular cocoa powder?

    We like to use Dutch prosses cocoa powder, because it gives the cake a deeper rich chocolate taste, and cocoa powder will work! It’s just a personal preference.

    How long will the cake last?

    This cake will last up to 5 days stored in the fridge. Cover the cake with plastic wrap or foil to prevent it from drying. This cake tastes amazing the day after.

    Can I use pecans instead of walnuts?

    Yes! You can use any kind of your favorite nuts in this recipe. Feel free to switch out the nuts for what you have available or for what you like best!

    Storing

    Store this dessert in the fridge (because it contains dairy) covered tightly with plastic wrap for up to 5 days. I like eating this the day after.

    Freezing

    Freeze this cake in an airtight freezer-friendly container for up to 3 months, and cover the cake with a few layers of plastic wrap.

    When ready to thaw, place the cake at room temperature for a few hours or overnight in the fridge.

    Variations

    Add-ins- make this recipe your own and add your favorite add-ins: chocolate chips, chopped walnuts, chopped pecans, mini chocolate chips, chocolate chunks, banana slices, chopped fruit, etc.

    Nutella- for a delicious Nutella flavor, add ¼ cup of Nutella to the mixture.

    Peanut butter- add ¼ cup of creamy or crunchy peanut butter to this cake to give this cake a chocolate peanut butter flavor.

    Substitutions

    Dairy-free- to make this cake dairy-free, replace the butter with vegan butter. Do not use margarine, it has a bad flavor and will ruin your cake.

    Gluten-free - if you want to make this recipe gluten-free, simply replace the biscuits with gluten-free ones.

      My late mother made something called cocoa pie, with social tea biscuits, cocoa, butter and wine. She kept it in the freezer and we loved it. I have been looking for a similar recipe for years! I’m going to add some type of liquor to this recipe and hope it brings back tasty memories. Thank you!
